Pilot study of a Foley catheter with micropore-delivered analgesia for reducing catheter-associated pain and discomfort in patients with repeated catheterizations
Authors' conclusion
Our findings indicate that the novel catheter provides early pain control, reduces postoperative analgesic needs and lessens storage symptoms after catheter removal, improving patient satisfaction.
